Ruling on a man marrying his father’s wife’s sister

Question:
Is it permissible to marry the sister of one’s father’s wife?

Answer:
Yes, there is nothing wrong with the sister of your father’s wife. There are two daughters: your father took one, and you take the other, so there is no harm; your father has one, and you have one. Likewise, if it is her daughter from another man, and he has not had intercourse with her—meaning the wife’s daughter from another man, and he has not had intercourse with her—it is permissible for you. However, if he has had intercourse with her, she becomes your father’s stepdaughter and is forbidden to your father, but she is permissible for you because she is not your sister; rather, she is your father’s stepdaughter, provided she is from another husband, whether before or after him.
So the point is: it is permissible for you to marry the sister of your father’s wife, her paternal aunt, her maternal aunt, and her daughter from another man, provided there is no breastfeeding relationship. Yes.
